Free Photo Shop? Not in this lifetime.... But there are several nice programs you may wish to consider instead. The Mac App store is currently selling "Pixelmator" for $14.99. It's not Photoshop, but it's very easy to use with lots of on line free help. There is also the "Gimp" which is open source and free, however, it's not as easy to setup and get working right. Requires a bit of patience but is a powerful program.
